Sorry, sorry, the value of the string is "signal (1.0) 125458" (and the value at that point in time) It is a communication with BCI2000 and I can not modify the data you send me the program, I'm trying to make a connection in real time.For processing these signals.

Then you need to parse out the string. If it is empty, do nothing. If it is each of the other things, then you put the value in the appropriate chart. One parse, one case structure. Not multiple parallel things.
